Do you go to Disney World often or is this a once every few years, special trip? If it is not somewhere your family goes frequently, could you wait a month to start or would you loose your motivation? I think, for me anyway, it would be better to postpone the diet, go to Disney World and then when you get home go full throttle on the Ideal Protein. That being said, I am going soon as well and I just plan on bringing my food along, grabbing salads for lunch and dinner. I'm sure it won't be the easiest thing to do but Disneyland food almost always looks waaaayyy better than it tastes and I will save a ton of money by not buying all of those Mickey shaped treats. Plus, in the past when we would go to Disneyland, my stomach was always wrecked by the time we would leave.... Good Luck and let us know how it goes!!!
